Stinespring theorem (cont.)
Abstract: In this talk we will formulate and proof the Stinespring dilation theorem. This theorem states that any completely positive linear map from a C*-algebra to a space of operators on a Hilbert space may be represented as a composition of a *-homomorphism and a suitable operator map. We also comment on the relation between positivity and complete positivity. Talk is based on the paper "Positive functions on C*-algebras" by W. Forrest Stinespring (1955).
